        Secondary curvature
    - - Kyphosis
        
        Primary Curvature
  - - - Segmental Arteries come from the vertebral artery
      - The vertebral artery comes from the subclavian Artery
    - - Posterior intercostal arteries are main supply for thoracic region
    - - Main supply of blood comes from the abdominal aorta into segmental Arteries
